Title: Fixing a second bug identified in issue #44

When there was a duplicate letter in a string, it would count the first occurrence of the letter, which means that it thought there was a letter transposition, when that wasn't the case. Added explicit check to see if there was an exact string position match first, then check to see if there is a matching letter in the "match window"
